Installation

Desktop Version

The desktop version is the easiest way to get started. It includes all the necessary components in a single installer, including an embedded PostgreSQL database.

Requirements

  • Operating System: Windows 10/11 (64-bit)
  • RAM: 8 GB minimum (16 GB recommended)
  • Disk Space: 2 GB for installation

Installation on Windows

  1. Download the QANode Setup.exe installer from https://www.qanode.com
  2. Run the installer and follow the instructions
  3. When finished, QANode will open automatically

On first launch, QANode will:

  • Initialize the embedded PostgreSQL database
  • Create the necessary tables (automatic migrations)
  • Start the API server
  • Open the application interface

Note: The first startup may take a few extra seconds while the database is being prepared. A splash screen will be displayed during this process.

Data Folder

The desktop version stores its data in:

%USERPROFILE%\AppData\Roaming\QANode\
├── pg-data/         # Embedded PostgreSQL data
├── storage/         # Artifacts (screenshots, PDFs, etc.)
└── custom nodes/    # Local custom nodes

Important: Never manually modify the files in pg-data/. Use the QANode interface to manage your data.

Troubleshooting

The desktop version does not start

  • Check that another instance of QANode is not already running
  • Try running as administrator
  • Check that port 5432 is not in use by another PostgreSQL instance
